Abstract: 686,060. Cleaning garments or fabrics. RICHTERKESSING, F. H. March 5, 1951 [March 6, 1950], No. 5238/51. Class 138 (i). A garment or fabric article spotting board comprises a main board 3, Fig. 3, a sleeve board 4 swingable to and from an operative position in relation to the main board, suction lines 34, 34<SP>1</SP>, Fig. 5, for each of the boards, a support for the boards having a pair of ports 28, 36 and adapted to provide a bearing for a movable valve element 42, a source of suction in fixed communication with the port 28 the other port 36 being in communication with the suction line 34 of the board 3, the valve element 42 having a passage 47 therethrough for registry with the ports 28, 36 so as to provide suction for the board 3, and a hollow supporting arm 44 for the board 4 mounted on the valve element 42 also to move therewith the valve element having a passage 46, Fig. 5, to register with the port 28 when the board 4 is swung to its operative position so that suction is then applied to suction line 34 the board 4. The support for the boards comprises a hollow member 2b telescopically adjustable by a screw 23 in a pedestal 2a. The top of the member 2b is formed with a plate 27 provided with the port 28. Fixed in horizontal spaced relation with the plate 27 by bolts 38 and spacer sleeves 39 is a plate 37 secured to the board 3 and provided with the port 36. The upper portion of the pedestal 2a forms a vacuum chamber and trap 22 connected by a passage 24 with a steamejector 19. The valve 42 comprises two ports 48, 49, Fig. 6, secured against relative angular movement and resiliently urged apart by a rubber gasket 52 so that the ports make fluid tight contact with the plates 27, 37. The lower port 49 of the valve member which includes the passage 46 is pivoted to the plate 27 at 43, Fig. 8, and the angular movement of this valve part is limited by the spacer sleeves 39. The upper port 48 of the valve which moves with the port 49 is provided with the through passage 47. When the suction is applied to the board 4 the port 36. is closed by a lateral extension 53 formed on the valve port 48. A vertical projection 54 on the extension 53 slidably engages in a recess in the top of the port 49 to lock the ports 48, 49 against relative angular movement. The apparatus is provided with a chamber 9, the major portion of which constitutes a steam chest the lower portion of which forms a condensate trap. The steam chest has inlet and outlet steam connections 10 and 12. The smaller portion of the chamber 9 is formed as a compressed air chamber supplied with heated compressed air through an inlet 11 (not shown). Four valves 8<SP>1</SP>, 7', 6a and 6b, Fig. 4, are disposed on the top of the chamber 9. The valve 8' connects with the air chamber and is operable by a foot pedal 8 and the valve 7' connects with the top of the steam chest and by a pipe 18 with the ejector 19, and is operable by a pedal 7. The valve 6a connects with the top of the steam chest and the valve 6b with the bottom of the chest (by a pipe 15). The valve 6a is operated by the initial depression of a foot pedal 6 while 6b is operated on further depression of that pedal. Both valves 6a, 6b are connected to a flexible tube 13 provided at its end with a spray gun 14. The valve 8' also connects with the tube 13 by a pipe 21. By operating the pedals either dry or wet steam or heated air may be supplied to the gun 14. Suction may be applied to the perforated ends of either table, according as to which is in use, by operating the pedal 8 to cause the ejector to function. Removed solvents, condensate lint and the like are prevented from entering the ejector by the trap 22 which may be emptied by a cock D into a receptacle R. A garment support 5 is provided under the spotting boards.
